Abstract
The utility model provides a wiper motor which can be used for eliminating the problem of axial running of worms, improving the performance of the motor and delaying the service life of the motor and comprises the motor and a gearbox, wherein a shaft hole is arranged on the gearbox, a worm wheel and a worm are arranged in the gearbox, an output end of the motor extends into the gearbox through the shaft hole on the gearbox and is linked with the worm, a bearing is also sleeved on the worm, and the bearing is positioned in the shaft hole; and the wiper motor is characterized by also comprising an axial limiting part, wherein the axial limiting part is sleeved on the worm and forms the axial limiting match of the worm. The wiper motor has the beneficial effects that: a spring clamping spring abutted against a spring performs the action of fixing the spring, and the spring can perform the actions of cushioning and reducing an axial running force; and a combined limiting part of a shaft sleeve and a shaft-sleeve clamping spring performs the action of limiting the worm to run towards the other side relative to the positioned side of the spring. Therefore, the abrasion of the worm is reduced, the noise and the vibration of the motor when working are improved, the durability of the motor is improved, and the performance of the motor is improved.
Description
Technical field
The utility model relates to a kind of motor, especially a kind of hydroelectric machine of scraping that is used for automobile wiper.
Background technology
Scrape hydroelectric machine as the driving mechanism of automobile wiper and indispensable, at present, the hydroelectric machine of scraping on the market generally comprises motor and reduction box, be provided with worm and gear in the reduction box, reduction box is provided with axis hole,, motor output end stretches in the reduction box and with worm screw by the axis hole on the reduction box and links, thereby drives automobile wiper by worm-wheel shaft output then.Be arranged with bearing on the worm screw, bearing is positioned at axis hole, reduces the friction between worm screw and the axis hole thus, and avoids worm screw moving along the string that worm screw directly makes progress when work.But, because technologic deviation when installing, and the wearing and tearing between each parts increase gap to each other gradually after long-time the use, thereby the string that the generation worm shaft makes progress is moving, cause the wearing and tearing aggravation between the worm and gear, shorten useful life, and increase the operation noise, influences a large amount of losses in the process of transmitting of motor power output.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of problem of eliminating the worm screw axial motion, improves motor performance, and the hydroelectric machine of scraping that postpones electrical machinery life.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of hydroelectric machine of scraping, include motor and reduction box, reduction box is provided with axis hole, be provided with worm and gear in the reduction box, motor output end stretches in the reduction box and with worm screw by the axis hole on the reduction box and links, and also is arranged with bearing on the worm screw, and bearing is positioned at axis hole, it is characterized in that: also include axial limiting spare, this axial limiting spare is sheathed on the worm screw and constitutes the axial limiting cooperation of worm screw.
Of the present utility modelly further be set to: described axial limiting spare includes spring and the spring jump ring that is sheathed on the worm screw, and an end and the bearing of described spring are inconsistent, and the other end and spring jump ring are inconsistent.
Of the present utility modelly further be set to: described axial limiting spare also includes axle sleeve and the axle sleeve jump ring that is sheathed on the worm screw again, one end and the bearing of described axle sleeve are inconsistent, the other end and axle sleeve jump ring are inconsistent, and described axle sleeve is positioned on the bearing opposite side with the inconsistent side of spring.
The beneficial effects of the utility model are: this axial limiting spare has spring and spring jump ring and axle sleeve and two groups of unit constructions of axle sleeve jump ring to form successively, the spring jump ring of conflicting with spring then plays fixing spring, it can be shifted because of the power of axial motion, and spring then can play buffering and reduce the power of axial motion; The combination locating part of axle sleeve and axle sleeve jump ring is installed in the opposite side of spring place, bearing place side, plays the restriction worm screw and moves to the opposite side string with respect to spring place side.Thus, reduced the wearing and tearing of worm screw, noise when improving machine operation and vibration, the durability of raising motor has improved motor performance.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the cutaway view of the utility model embodiment.
Embodiment
As shown in Figure 1, present embodiment includes motor 1, reduction box 2 and axial limiting spare 3, reduction box 2 is provided with axis hole 21, be provided with worm gear 23 and worm screw 22 in the reduction box 2, motor output end 11 stretches in the reduction box 2 and with worm screw 22 by the axis hole on the reduction box 2 21 and links, also be arranged with bearing 4 on the worm screw 22, bearing 4 is positioned at axis hole 21, this axial limiting spare 3 includes spring 31 and spring jump ring 32 and axle sleeve 33 and the axle sleeve jump ring 34 that is sheathed on the worm screw 22, one end and the bearing 4 of described spring 31 are inconsistent, and the other end and spring jump ring 32 are inconsistent; One end and the bearing 4 of described axle sleeve 33 are inconsistent, and the other end and axle sleeve jump ring 34 are inconsistent, and described axle sleeve 33 is positioned on the bearing 4 opposite side with spring 31 inconsistent sides.
In the utility model, this axial limiting spare 3 has spring 31 and spring jump ring 32 and axle sleeve 33 and 34 liang of groups of axle sleeve jump ring unit construction to form successively, 32 of the spring jump rings of conflicting with spring 31 play fixing spring 31, it can be shifted because of the power of axial motion, and 31 on spring can play buffering and reduce the power of axial motion; The combination locating part of axle sleeve 33 and axle sleeve jump ring 34 is installed in the opposite side of bearing 4 place's springs 31 place sides, plays restriction worm screw 22 and moves to the opposite side string with respect to spring 31 place sides.Thus, reduced the wearing and tearing of worm screw 22, noise when improving machine operation and vibration, the durability of raising motor has improved motor performance.The utility model can also have other execution modes, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
